Both the dual upper and lower gates were design for hydraulic operation and were capable of rotating from 0 to 90 degrees about the vertical tube
of the frame.
The entire head could be rotated about the horizontal tube of the frame to enable various pile driving rakes. The complete frame was mounted on a
sliding table to permit lateral translation in both the port-starboard and bow-stern directions.
